Introduction: Essure® device malposition is a rare, but clinically significant complication, for which management is idiosyncratic. This case report describes an unusual example of Essure® migration in order to clarify reasonable management options. Case Presentation: A 50-year old G4P2022 underwent hysteroscopi...

In continually increasing area and structure of modern power system having burden demand uncertainties, the use knowledgeable vigorous frequency strategy is essential for satisfactory functioning Power system. A combined fuzzy proportional-integral-derivative (CFPID) controller suggested supervision To optimize parameters, a review sine cosine work adjusted improved whale optimization algorithm...

We use Instant Preheating as a mechanism to reheat the universe when its evolution is modeled by non-oscillating background. Once we obtain reheating temperature, calculate number of e-folds using two different methods, which allows us establish relationship between temperature and spectral index scalar perturbations. explore this connection constrain for Quintessential Inflation models.

This paper presents a comprehensive analysis and comparison of air-cored axial flux permanent magnet (AFPM) machines with different types of coil configurations. Although coil factor is particularly more sensitive to coil band width and coil pitch in air-cored machines than conventional slotted machines, remarkably no comprehensive analytical equations exist. Here new formulae are derived to co...

In this paper, an improved Simulated Annealing algorithm for Protein Folding Problem (PFP) is presented. This algorithm called Cluster Perturbation Simulated Annealing (CPSA) is based on a brand new scheme to generate new solutions using a cluster perturbation. The algorithm is divided into two phases: Cluster Perturbation Phase and the Reheat Phase. The first phase obtains a good solution in a...

Observations made during the last ten years with the Chandra X-ray Observatory have shed much light on the cooling gas in the centers of clusters of galaxies and the role of active galactic nucleus (AGN) heating. Cooling of the hot intracluster medium in cluster centers can feed the supermassive black holes found in the nuclei of the dominant cluster galaxies leading to AGN outbursts which can ...

A comprehensive digital computer model of the two-area interconnected power system including the governor deadband non-linearity, steam reheat constraints and the boiler dynamics is developed. The improvement in AGC with the addition of a small capacity Superconducting Magnetic Energy Storage (SMES) unit is studied. Time domain simulations are used to study the performance of the power system a...

This paper presents optimal AGC regulator design of deregulated power system based on the full state feedback control strategy. The two-area interconnected power system of identical nature consisting of non-reheat turbine is considered for the investigations. The areainterconnection of the power system via parallel EHVAC/HVDC transmission link is considered. The proposed controller is applied t...

We calculate the constraints on the primordial curvature perturbation at the end of inflation from the present day abundance of Primordial Black Holes (PBHs), as a function of the reheat temperature TRH. We first extend recent work on the formation of PBHs on scales which remain within the horizon during inflation and calculate the resulting constraints on the curvature perturbation. We then ev...
